Clinical Information

Reference Intervals 2.2 - 2.6 mmol/L  
Test Method Abbott c8000 series analyser using Abbott reagents.

Comments

All Calcium requests will be reported with a corrected calcium value.

Corrected Calcium = Calcium + 0.012*(39.9 - Albumin)

Prolonged stasis during venepuncture and haemolysis will give false high values 

For baseline level, patient should be fasted for 12 hours and seated for 20 minutes prior to specimen collection.
